"Dx51d" yog tus qauv tsim qauv qib steel, feem ntau siv los qhia cov hlau kub-dip galvanized. Cov khoom siv hluav taws xob ntawm DX51D steel tuaj yeem sib txawv raws li yam xws li muaj pes tsawg leeg, kev ua, thiab tuab. Feem ntau, cov khoom siv ntawm kub-dip galvanized steel, suav nrog DX51D, yuav suav nrog:
| Khoom | Tus nqi |
|---|---|
| Hom khoom | DX51D hlau |
| Tensile zog | 270 - 500 MPa |
| Yield zog | 140 - 300 MPa |
| Elongation | 22 feem pua - 38 feem pua |
| Hardness (Rockwell B) | 50 - 70 HRB |
| Young's Modulus | 200 GPa |
| Poisson tus ratio | 0.30 |
| Qhov ntom | 7.85 g / cm³ |
| Thermal Expansion | 10.4 x 10⁻⁶ / degree ({3}} degree) |
| Hluav taws xob conductivity | 56.2 MS / m (ntawm 20 degree) |
Tensile Strength: Qhov siab tshaj plaws ntawm cov khoom siv tuaj yeem tiv taus yam tsis muaj kev tawg. Nws feem ntau ntsuas hauv megapascals (MPa).
Yield Strength: Qib kev ntxhov siab uas cov khoom pib nthuav tawm cov yas deformation (qhov hloov pauv mus tas li). Nws kuj tseem ntsuas hauv megapascals (MPa).
Elongation: Qhov feem pua nce ntawm qhov ntev ntawm cov khoom ua ntej nws tawg thaum lub sij hawm ntsuas tensile. Nws muab ib qho kev qhia ntawm cov khoom ductility.
Hardness: Cov khoom tsis kam rau indentation lossis khawb. Nws feem ntau ntsuas ntawm Rockwell nplai.
Formability: Lub peev xwm ntawm cov hlau yuav khoov, ncab, lossis tsim yam tsis muaj kev tawg lossis tsis ua haujlwm.
Corrosion Resistance: Thaum tsis yog cov cuab yeej cuab tam, qhov corrosion kuj ntawm kub-dip galvanized steel, nrog rau DX51D, yog ib qho tseem ceeb yam ntxwv vim zinc txheej.
Impact Resistance: Lub peev xwm ntawm cov khoom siv los nqus lub zog hauv kev cuam tshuam kev thauj khoom.
